AC'D'UA'IING MECHANISM.

Specification of Letters Patent.

Application filed February 2; 1911. Serial No. 606,126.

To all whom 'it may concern:

Be it knownv that I, GEORGE SIM: a citizen of the United States,residingat'Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Actuating Mechanism, ,of which the followingis a specification. My invent-ion relates particularly to ac tu'atingmechanism for oscillatory washing machines.

My primary objectis to improve and simplify such. mechanism.

My invention is illustrated in its preferred embodiment in theaccompanying drawings, in which g Figure 1 represents an end elevationalview of a washing machine equipped. with my improvements; Fig. 2, abroken section,

a vertical section taken as indicated at line 3 of Fig; 1.; and Fig. 1,a broken sectional perspective view,showing a detail of asedimerit-chamber employed.

In the construction illustrated, A rep:- resents a frame;' B, anoscillatory tub. or body, having horizontal trunnions pivoted "on theframe; and C, actuating'mechahism for the member B.

The frame A may be of any suitable con! struction. As shown, itcomprises end standards 1; a connecting member 2;. and braces 3. Thebody B is of somewhat oval form, viewed at the end; It has flat ends 4,a curved bottom 5 terminating at enlargements 6, inclined side members7, and a removable top 8'. The body B is equipped at the lower portionsof the outer surfaces of its end members 4 with castings or metalmembers 9 having upper arms 10 and lower arms 11. .The members 9 haveoutwardly turned horizontal trunnions 12 supported in journals orbearings 13 with which the upper ends of the standards 1 are equipped.One of the castings or members 9 serves as a combinationspring-attaching and trunnion-carrying member, having connected. withstuds 14 projecting outwardly from the lower ends of the arms 11, recoilsprings 15, whose lower ends are connected with studs 16 carried bymetal members or castings 17 applied to the end standards 1 of the frameon opposite sides of the axis of the tub or body B. The member 9referred to is equipped above its trunnion 12 with a stud 18 upon whichis pivoted the lower end of stated briefly.

the lever 19 of the actuatingmechanism C.

Attached to opposite edges of the lever 19 are power transmissionsprings 20,. whose the end member 4 of the; tub. Above the springs 20the lever 19 works; in a: horizontally disposed guide 23 carried bytheupper portion of the end member 4 of the-tub. The guide 23 comprisesan inner plate or bar 24=and an outer plate or bar 25 sepa- PatentedFeb. 20,1912.

- remote ends are connected with studs 21 carrled by plates or castings22 connected with rated by a space 26 adapted to accommodate the lever19,.and springs 27 confined between the lever 19' and the end port-ionsof the guides. 1The lever 19 may be actuated in any suitable manner.. Itis shown equipped .at its upper portion with ahandle 28"for manualoperation taken as indicated at line 2 of Fig. 1; Fig.3,

The tub' B has its bottom 5 made with a forannnous. central portionprovided with small perforations, as indicated at 29, and

portions of the hafile'plates are separated, by a space 33, whichcommunicates with the perforations 29, and the baffle plates are set atan angle to each other, the plate 32beg made somewhat narrower than theplate 31,50 that the plate 31 will overlap the free edge ofthe plate 32but will be-separat'ed therefrom by a space 34. Sediment may thus passthrough the perforations 29 and between the bafile plates, dropping intothe beneath the foraminous portion ofthe tubf bottom is a sedimentchamber 30, into which depend bafile plates .31 and'32; which arecarried by the bottom 5. The upper edge lower portion'of thesediment-chamberpand the baffle plates will serve to 'prevent thesedimentfrom being stirred up and thrown bagk into the tub duringoscillations of the tu The operation of the mechanism may be Motion iscommunicated to the lever 19, as by meansof the handle 28, and power istransmitted through. the coil springs 20, as the lever 19 isreciprocated, thereby oscillating the body B. As the body oscillates,the recoil springs 15 are alternately placed under tension, thus servingas counterbalancing springs tending to re turnv the tub to its uprightposition. and so aiding in the actuation of the tub. The

coil springs 27 when employed,- serve the same function as the coilsprings 20, or

rather supplement the springs 20. In practice, one set of powertransmission springs may be omitted, if desired. Preferably, however,the springs 20 will be retained. As the lever 19 is oscillated, itsreciproeating vmovements are transmitted to the tub, but amplified atthe tub, owing to the momentum of the tub and its contents.

The construction described is exceedingly simple, may be cheaplymanufactured, and

latory body, a combination spring-attachis thoroughly effective for itspurpose. It may be supplied to householders at eom- 'paratively smallexpense, and requires but little power, to operate it.

What I regard as new, and desire to secure by Letters Patent, is:

l. The, combination of a. frame, an osciling and trunnion-carryingmember secured toone end of said body and having a horizontally disposedtrunnion journaled in said frame, recoil-springs having their upper endsattached ,to said member on opposite sides of the trunnion and havingtheir lower ends connected to said frame, a lever pivoted on said memberand rising therefrom, and power-transmission springs on opposite sidesof said lever and connected with said body.

2. The combination of a fraihe, an oscillatory body, a combinationspring-attaching and trunnion-carrying member secured to one end of saidbody and having a horizontally disposed trunnion journaled in saidframe, recoil-springs having their upper 5 ends attached to said memberon opposite 3 sides of the trunnion and having their lower endsconnected to said frame, a lever pivoted on said member and risingtherefrom, and power-transmission springs on opposite sides of saidlever having their ad acent ends attached tosaid lever and their remoteends attached to said body.

3. The combination of a frame, an oscillatory body having horizontalpivots journaled on saidframe, a lever pivoted to naled on said frame, alever pivoted to swing 'in'a vertical plane parallel with an end of saidbody, a guide for said lever carried by said body above the pivot ofsaid lever, power-transmission springs having their adjacent endsco-acting with said lever and having their remote ends connected withsaid body, and recoil-springs having their upper ends attached to oneend of said body on opposite sides of a pivot and having their lowerends attached to said frame beneath the body-pivot.

' 5. The combination of a frame, an oscillatory body having horizontalpivots journaled on said frame, a lever pivoted to swmg in a verticalplane parallel with an end of said body, a guide for said lever carriedby said body above the pivot of said lever, coil springs confined in.said guide at opposite sides of said lever," power transmission springshaving their adjacent ends con nected with'said lever beneath said guideand having their remote ends connected to said body, and recoil-springsconnected with said body and with said frame.
